Diagnostics
The switch software includes a set of diagnostic programs that perform basic
checks of all system components. These diagnostics do not run with normal
operating code and require that the system be totally dedicated to their use.
The switch does
not
perform switching operations when diagnostics are
running.
Caution
Diagnostics are designed to be run by service personnel only. This
section is
not
intended as a guide to the diagnostics software. Detailed
knowledge of how the switch hardwre functions is necessary in order to
effectively use these diagrnostic programs. For more information, contact your
authorised Allied Telesis distributor or reseller.
To enable diagnostics mode:
1.
Connect a terminal to the RS-232 terminal port (ASYN0).
Using a terminal cable, connect a terminal to the RS-232 port (ASYN0) on
the switch. See
“Cables” on page 14
for more information on terminal
cables. Set the terminal communication parameters to the following:
•
Baud rate: 9600
•
Data bits: 8
•
Parity: None
•
Stop bits: 1
•
Flow control: Hardware
2.
Restart the switch.
Restart the switch, either by using a pen or pencil to operate the recessed
RESET button on the switch’s front panel, or by using the terminal to log in
and enter the command:
restart reboot
